CBM performance for the measurement of strange hadron and hypernuclei in 3 GeV Au+Au collisions at FAIR — •Yingjie Zhou for the CBM collaboration — GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany

The main goal of the CBM experiment at FAIR is to study the behavior of nuclear matter at very high baryonic density. This includes the exploration of the high-density equation of state (EoS), search for the transition to a deconfined and chirally restored phase and critical endpoint. The promising diagnostic probes for this new state are the enhanced production of multi-strange (anti-)particles. The CBM detector is designed to measure such rare diagnostic probes multi-differentially with unprecedented precision and statistics. Important key observables are the production of hypernuclei. The discovery and investigation of new (doubly strange-)hypernuclei and hyper-matter will shed light on the hyperon-nucleon and hyperon-hyperon interactions.

In this presentation, performance studies for strange hadron and hypernuclei production in 3 GeV Au+Au collisions with the CBM experiment at FAIR will be presented. The CBM performance is compared with that of the STAR experiment and projections for statistical uncertainties with high statistics data at CBM are presented.
